IMPROVEMENT lN OSCILLATING ENGINES.

Specification forming part ot' Letters Patent No. 48,563, dated July 4, 1865.

andthe letters of reference marked thereon.

'The nature of my invention consists in a novel arrangement and construction 'of parts in the class of steanrengines known as oscila lating" or "vibrating" cylindersteamengines,

by means of which I am enabled to use a directacting valve-gear to operate the sliding valve without the adjustment of thc valve being sensibly affected or impaired by the oscillatin g motion of the cylinder, and in doing this I am -at the same time enabled to preserve a simplieity of parts cheaper to construct and easier 4to adjust, cleanse, and repair when worn than 4 have been heretoforeemployed torthe samepurpose.

I will now proceed to describe particularly and exactly the construction and `operation of my invention.

Figure l exhibits a side elevation ot' the engine; Fig. 2, a sectional elevation, and Fig. 3 an end. elevation, of the same.`

A is the cylinder, supported by and oscillat ingon the trunnionsH and H' in the bearings G and G', securedyto the bed-plate It. Y

y B is the pistonrrod, attached directly to the crank G upon theextremity of the revolving shaft D, which shaft is supported by the uprights or standards E and E', secured to the. bed-plate F. Upon the shaft D is fixed an eccentric, Q, which, by means otl the rod l?, imparts a reciprocating motion to the slide N, which` is free to slide vertically in theguide O attached to the frame E. The lower portion of the slide Nis formed with a curved slot, W,

having such a radius that it is concentric with the axial line of the cylinder-trunnions when the slide N is in mid-travel. In this slotW is a roller, M, attached to the upper portion of thevalvestem or rod L, which rod is secured to the valve It in the steam-chest I, and `controls the admission and egress of steam through the channels S and S' to and from the cylinder A, the escape or exhaust steam passing through the cavityV in the valve R, through the chann el T, which leads around the cylinder A, to the opening U `in the trunnion H', whence it .is discharged.

K is an opening in the lid of the steam-chest I, through which steam is admitted by a .steampipe connected by any of the known forms of stuffing-boxes placed concentric with the axis of the cyliuder-trunnions.

The peculiarity of this invention consists in passing the channels S, S', and T through the trunnion H, and in the use ot the direct-acting valve-gear constructed with the slotted slide N, roller M, and valve-stem L, in combination with a steam-chest located relatively to the trunnion H and cylinder A as described. In other respects the operation of the engine is similar to others in general use. It is apparent upon inspection that the steam-chest I, valve-stem L, and rollerlVI areffree to vibrate with the cylinder A, and at the 'same time the motion of the valve R imparted by the eccentric Q is unaected bythe vibratory motion of the cylinder.

What I claim as my invention, and desire to secure as such by Letters 4Patent, ifs- 1. The arrangement of the channels S, S', and T through the trunnion H, substantially in the manner described and shown.

2. Arranging the steam-chest relatively to the trunion H and cylinder A substantially as set forth.

3. The construction and arrangement of the valve-gear hereinbetore described, in combi- V nation with the steam-chest, substantially as herein set forth.
